This trial has been completed.
|Condition||type 1 diabetes|
|Phase||phase 1/phase 2|
|Sponsor||University of California, San Francisco|
|Collaborator||Juvenile Diabetes Research Foundation|
|Start date||February 2004|
|End date||December 2016|
|Trial size||30 participants|
|Trial identifier||NCT00501709, 39-42C|
Pancreatic islets are the part of the pancreas that produce insulin and help control the blood sugar. This study aims to improve islet transplantation as a treatment for Type 1 Diabetes by using a new combination of immunosuppressive drugs that have been successful in treating other autoimmune diseases and in preventing kidney transplant rejection.
|Endpoint classification||safety/efficacy study|
|Intervention model||single group assignment|
time frame: monthly
Male or female participants from 18 years up to 65 years old.
